They haven't been replacing retirees. And the union has been letting them get away with it.
That has been going on in my area. Since we are working under the old contract there better not be any casual working tomorrow or I'm saying something to my Steward that since they are working after the 31 they must be FT drivers now.
Under the new contract casual can work till the 15 of January. Under the old it Dec 31.
